Lycett was owned by Brooks. Your saddle, like Brooks and Wrights, came in both a standard and narrow version. So if it's the narrow, it's the same as a Wrights W3N and almost the same as a Brooks B5N. The frame is the same as that used on B.15 or B.17 saddles, but no eyelets in the bag loops. Like a Brooks or Wrights saddle, it may have a date code stamped on the underside of the cantle plate (73 C, for example, would mean 3rd quarter of 1973).

In terms of quality, I believe the leather is of a somewhat lower grade than a B.15, but at this point --your saddle is 40 or 50 years old-- the present condition of the leather is probably more important than its original quality level. We can only guess how it will hold up; I've seen many saddles tear right in half, though they looked as good as yours only moments before they tore. if that happens, be sure to save all the pieces, and sell them to me.
